Question

i am currently working on a student registration and lecture attendance system using biometric technology. i have my database using Microsoft Access and i have forms to access the tables for registration/enrollment.Now there is another interface in which i am supposed to compare at runtime an image received from a fingerprint scanner into an image box and the images in the database for a match or otherwise return NIL.i need help in automatically loading the image produced by the fingerprint scanner into the imagebox and to compare the images or if there is any suggestions on how to go about my project, will be very much appreciated 

Answer 1

I would expect your biometric interface to come with software that offers some API which can determine if a scanned finger print matches a pre-registered one.

Doing this yourself by trying to "compare" two images will be difficult verging on impossible.  Not to say it can't be done at all, but it would be difficult for even an experienced programmer.  Consider that if the scanned finger print is 1 pixel to the left or right of the saved image, you won't have a pixel-for-pixel match.

Investigate the scanner and its included software and determine how to ask the scanner software to validate a finger print for you.

Answer 2

thanks. the scanner is only for creating the images but it is not for verification since it has no software of the king.i was hoping o get help on creating an API or just an interface which will compare a current image with an already enrolled image

Answer 3

You might google ".Net Windows Image Acquisition " or ".Net Twain".  Check to see if your scanner supports either of those interfaces.

Do you see any link in the Related Topics frame that looks like it applies to your subject?  Do you really want to read about "urgent" subjects?  Neither do most responders.  Maybe a better subject would assist you in urgently finding appropriate links for your task.

Then I would suggest you have the wrong type of scanner.

An ordinary image scanner cannot reliably read fingerprints.  The image left by the natural oil and dirt of any finger degrades the images after a few scans to the stage where nothing can be ascanned reliably.  You need a scanner specially constructed for the task, which will have a surface that copes with these contaminants.  It will also have the software you need to compare scanned images to the database.

Did you look at what Reed posted ? If not I suggest you do so.
